,Application filed June 13, 1902i Serial No. 111,518. (No model.)

To @ZZ whom it may concern:

Be it known that I, FREDERICK W. HEN- NINGER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Machines for Cleaning, Straightening, and Reinsulating Old Wire; and I declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to Vthe accompanying drawings, which form a part of this specication.

My invention relates to an improvement in machines for cleaning, straightening, and reinsulating old wire, shown inthe accompanying drawings and more particularly described in the following specification and claims.

Referring to the drawings, Figure l is a perspective view showing the wirein-tl'e act of being cleaned of the old insulation, straightened, and wound with new insulating-tape. Fig. 2 is a sectional view through the tapereel. Fig. 3 is a perspective view of one of the cutting-disks composing one of the rolls for freeing the wire of the old insulation.

Referring to the letters of reference shown in the drawings, A A are standards designed to support the frame B. At one end of the.

frame B is journaled the roll D, composed of a series of cutting-disks d, assembled together on the shaft. E is another roll composed of a similar series of cutting-disks e, but preferably of smaller diameter, mounted on Vthe bell-crank lever E, pivoted at f to the frame B and adapted to come in close proximity to thecutting-disks of the roll D. Y The forward end of the bell-crank lever is sleeved to receive a screw-threaded bolt G, provided with a thumb-nut g', bearing on the lugs h2 of the frame.

g is a spring coiled around the bolt G and adapted to force the roll E into contact with the old insulation ou the Wire H.

It is obvious that the pressure of the cutting-disks may be increased or diminished by adjusting the thumb-nut g'.

I is a coil-spring designed to free the wire of the old insulation after the same has been cut in its passage through the rolls E and D. This spring is supported in the cup-shaped casting i 1.', the lower of which may be integral with the frame B and the upper bolted thereto.

I is a screw-threaded bolt provided on the inside of the casting i with a suitable disk (not shown) to engage the spring and designed to increase or decrease the tension.

J and J are tension-rolls, J being provided with an adj usting-screw j. The bearing for the tension-roll J is sleeved Within the dependinglugs h3 of the frame to insure against displacement. The tension-roll J is pivoted in the return-bend B of the frame B.

.K is a gear-case bolted to the frame B, inclosing a bevel-gear mounted on the shaft of the tension-roll J' and meshing with the gear L, inclosed within the gear-case K'.

M is a tape-reel supported on the angle-iron bolted to the gear L. This tape-reel is constructed with two disks 'm and m', the disk m being rigidly engaged with the angle-iron, While the disk m is free to rotate on the shaft m2. This shaft ou the inside is provided with anenlarged head m6, and at the opposite end is screw-threaded to receive a milled thumbnut m3. The shaft m2 is square at 'm7 to insure it against rotation. Coiled around the bolt, between the angle-iron and the thumbnut, is a spring m8, the tension of which is designed to bring the disks in frictional contact. I- prefer, however, to insert between the disks m and m a disk of paper or rubber fm:L for increasing the friction and to relieve the metal surfaces from wear. Secured to the disk m are spring-arms 'mito receive the roll of tape N.

To iix the frame at any desired angle when once adjusted, I provide an arc-shaped slot a in one or both of the standards A. Through this passes a bolt which engages the frame B. The shank of the hand-wheel is designed to impinge against the standard-and hold the frame at any angle desired within the compass of the quadrant. v

The operation of the device is as follows: The wire H as it is unwound from the old iieldcoil passes under the roll D and up between the cutting-disks of the rolls E and D, where the old insulation is shredded and otherwise disintegrated. After passing around the roll .D itis fed forward to and through the scraper- I, where the old insulation not previously re- ICO moved is cleared from the wire. The bare wire is then fed forward between the tensionrolls .I and J', which, with the other rolls and scraper, straighten the wire, taking lout any kinks that may be found in it. The friction of the wire on the roll J', due to its passage between the tension-rolls, rotates the gear housed within the case K, and it being in mesh with the gear L carries the spool of tape around the wire as it is fed out to the new field, and as it rotates it unrolls the tape and Winds it upon the wire. The tension governing the unwinding of the tape may be regulated by the thumb-screw m3.

Having thus described my invention, what I claim isl. In a machine for removing and restoring insulated wire, cutting-rolls adapted to receive the insulated wire between their cutting edges, means for removing the old insulation after being submitted to the action of the cutting-rolls and means for feeding the Wire through the cutting-rolls, substantially as described.

2. In a machine for removing and restoring insulated wire, cutting-rolls adapted to receive the insulated wire, consisting of a series of disks provided with cutting edges assembled together and suitably mounted and means for feeding the wire through said rolls, substantially as described.

3. In a machine for removing and restoring insulated wire, cutting-rolls adapted to receive the insulated Wire between their cutting edges, one of said rolls mounted in a iixed bearing, the otherin an adjustable bearing, the construction being such that the rolls are brought into cutting contact with the insulation on the wire as the Wire is fed through, substantially as described.

4. In a machine for removing and restoring insulated wire, cutting-rolls adapted to receive the insulated wire between their cutting edges, one of said rolls mounted on one end of a swinging lever, a bolt sleeved in the opposite end of said lever and having a sleeved engagement with the frame, a spring adapted to bring the roll in cutting contact with the insulation on the wire and means for increasing or diminishing the pressure of the cutters, substantially as described.

5. In a machine for removing and restoring insulated wire, a scraper for removing the old insulation consisting of a coiled spring through which the wire travels suitably mounted in the frame and means for regulating the tension of the spring, substantially as described. v

6. In a machine for removing and restoring insulated wire, tension-rolls through which the wire travels in its passage through the machine, one of said rolls mounted in an adjustable bearing, a set-screw engaging said bearing for regulating the tension of the roll on the wire, a tension-roll acting in conj unctiou with the adjustable roll mounted on a shaft in a xed bearing with a gear adapted to rotate the tape-reel around the wire, and said tape-reel, substantially as described.

7. In a machine for removing and restoring insulated wire, a tape-reel consisting of a fixed and loose disk, means for holding the disks in frictional contact and a disk m4 of paper interposed between said disks, substantially as described.

8. In a machine for removing and restoring insulated Wire, a swinging frame mounted in suitable standards, standards slotted for the passage of a bolt designed to engage the frame whereby it may be held at the angle desired, and the bolt and hand-wheel for setting the same, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
